If someone wants to know what to buy, I have a few recommendations here
RPG :
Dragon age : Origins
-------------------------
Definitely one of the best RPG's of the year. Graphics are amazing, the story is amazing. If you have played any Bioware games before (Baldur's Gate, Neverwinter Nights) and liked them, you will definitely love this!
9/10
Torchlight
-------------------------
Absolutely best hack'n'slash/dungeon crawler I've ever played (Shares first place with Diablo's :P).
Great gameplay, nice cute graphics, the story is quite good too. Def. worth getting if you like Diablo's and similiar games. And you can use mods to get it even better
9/10
Divinity II - Ego Draconis
-------------------------
One of the best RPG's too. Outstanding graphics, story and gameplay. Although you need a pretty good computer for it. But worth trying if you think you have good enough
8/10
Risen
------------------------
Haven't played it (yet :P) but adding from Remah's suggestion. Will add a better description once I get it.
Youtube vid tho :

First-person shooters :
Call of Duty : Modern Warfare 2
--------------------------
Outstanding gameplay, both singleplayer and multiplayer! Must-have if you like fps games. Multiple online game-modes, amazing graphics and single-player story.
9/10
If anyone has anything add, just tell me and I will add it to the list
